HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 707,144, dated August 19, 190%. Application filed August 16, 1897. Serial No. 648,393. on) model.)

ing drawings, is a specification, like characters on the drawings representing like parts.

In another application, Serial No. 625,873, filed by me on the th day of March, 1897, I have shown and described an apparatus for nailing heels and top lifts upon soles, the said apparatus containingdevicesby which to antomatically supply nails into a foot-plate to,

be transferred therefrom into anail-carrier,

but in said apparatus the foot-plate had to be I changed for every particular change in shape heel.

of the nailing or for different sizes or shapes of heels. apparatus shown in said applicationin such manner that a change "in the nailing or inthe This invention aims to improve the shape in which the driven nails shall stand in the'heel or for changein size or shape of heels may be made instantly and without changing the foot-plate. To dothis, instead of the footplate described in said application I have devised a foot-plate'comprising abottom plate and a top plate, and with said foot-plate I employ a series of movable nail-deliveries, each having a suitable nail passageor tube, the number of said deliveriesemployed depending upon the number of nails to be driven-into'a These deliveries are independent of each other and are movable independently with relation to the line of nailing. trol and determine the position of these independent nail-deliveries, I employ a pattern, herein represen ted as a plate, shaped to accord with the nailing desired, said pattern acting, preferably, against the nail-deliveries to con trol their position. The pattern will preferably be notched at its edges, and when inserted between the deliveries the notches will receive a part of each delivery and retain them spread in the positiondesired. I have provided means to guide the pattern when being put into its operative position. The

deliveries are 1 held yieldingly ,by suitable springs,'which act normally to press the de- To con-- liveries toward. the pattern. Each nail-delivery is connected with a flexibletube that is in turn connected at its opposite end with suitable nail-asserting mechanism.

Figure 1 of the drawings represents in front elevation a sufficient portion of a heel-nailing machine, which, taken in connection with the machine described. in said application, will enable my presentinvention to be thoroughly understood. Fig. 2' is a partial plan view in section below the dotted line a; with the shoeholder omitted. Fig, 3 is a plan view,enlarged, of a nail-block with a series of holes indicating a great variety of nailings which may be done with the same block. Fig. 4. is a top or plan view, much enlarged, showing a series of deliveries with a patternofone form to control their position; Fig. 5 is a side elevation under side view'ofFig. 4. Figs. 8 and 9 show difierent forms of patterns fordifferent nailings. Fig.-10 shows one of the gates detached, and Fig. 11 a modified form of pattern. In the drawings the framework A, the die-. bed spindle E the hopper b the raceways b the tubes b the means for asserting; the nails which slide down the said raceways into the said tubes, the arm b the nail-carrier 0, its arm 0, having a hub which is mounted loosely on a stationary stud 0 the handpiece 0 attached to said carrier; the gate 0 shown partially by dotted lines, said gate being pivotally mounted at c on the said arm 0 and having a finger t; the spring 3, connected at one end to arm 0' and at its other end to a projection 2 of the gate 0 said spring acting normally when permitted to swing. the

gate about the said pivot c to uncover the.

e; the pin 5 in the arm 0', entering a hole in the finger 4t andholding thegatecidn position to support the nails inthe nail-carrier; I

the stop ,7, (see Fig. 1,) against-whichsaid finger 4. strikes and is depressed to effect the release of .the gate 0 so that the spring 3 may turn said gate about said pivot c to the right, as shown by dotted lines in Fig. 2, so that the nails in the nail-carrier and resting on said gate may readily drop into the usual holes in the nail-block and onto the upper ends of the usual drivers d; the heel-holder D; the stud l8; on which it turns; the toplift holder D the breast-gage H for the breast of the heel back-part gage 71, the link f, the cam 61 for moving the heel-holder D at the proper times, the chain e the arm a the shaft 0., the lever 9 the yoke-like clamp 29*; forked arm w, carrying said clamp; the vertically-movable slide 28, the nail-block bed E and the screw 9 to stop the arm 0 in its normal or loading position, and the adjustable stop (1 to meet and effect the closing of the gate 0 are and may be all substantially as shown and described by like letters in the application hereinbefore referred to. So said devices need not be herein more fully described.

The novel devices illustrating the invention to be herein described and claimed, they having for their object the ready delivery of nails into any of the numerous holes in the usual nail-block, are applicable to the footplate shown in said application, they taking the place of the means contained in the footplate in said application to receive the nails from the tubes.

My invention provides for readilydist-ributing the nails for any line of nailing.

In order that this invention may be fully available, the holes in the nail-receiving portion of the nail-carrier 0 (see Fig. 2) and in the nail-block e, (see Fig. 3,) shown therein on a much larger scale, will or may be distributed substantially as indicated by the great number of holes therein, the nail-holes of the nail-carrier and nail-block of course coincidmg.

I have devised what I shall call a system of movable nail-deliveries, which receive the nails from the flexible tubes b said deliveries being freely movable, and when in opertion being controlled as to their positions by a suitable pattern, so that nails entering said deliveries may drop therefrom into any of the numerous holes referred to, the carrier 0 being so made and located as to adapt one and the same nail carrier and block for use with heels of varying size and shape. This nail-block,with the great number of holes arranged substantially as represented, is not herein claimed as novel.

Referring now to my invention, Fig. 4 represents a foot-plate which will be mounted upon or set into the curb at the outer end of the arm 19 common to said application, in stead of the foot-plate therein shown. The foot-plate as herein represented is composed of a bottom plate 1O and a top plate 12, sustained above it,the top plate resembling somewhat in shape a horseshoe and having a series of slots 13. The drawings show a series of lovers 15 occupying positions between said plates, each lever having at its inner end a nail passage or tube 16, constituting the essential part of what I have herein designated as a nail-delivery. The outer ends of the levers 15 have pins 14., that enter the slots 13, and said pins have connected with them one end of a spring, as 18, the opposite ends of said spring engaging pins 17, mounted, as shown, in the plate '12, said series of springs, one for each nail-delivery, acting to press the nail-deliveries normally to the center of the plate 10 (Indicated by line at in Fig.4:.) The bottom plate 1O (see Fig. 7) has an enlarged throat 72. shown as two open spaces, with a tongue 72. between, that sustains two pins or guides 77, ,said guides extending upwardlyand receiving the holes 77, of the pattern, said pins orguides accurately positioning the pattern. The nail-deliveries in their adjustment may move in any direction in the spaces 72/ and in whatever position they are held by the patternthey will be left over suitable holes in the perforated portion of the nail-carrier. The pattern is confined in working position after it has been applied to the guides 72. by means of a screw h The bottom and top plates 10 and 12 are clamped firmly together by means of astud-screw it (see Fig. 6) and a nut h (represented as L-shaped,) said nut having a detachable handle 7L9, the handle being serviceable when it is desired to change one of my improved foot-plates for another one having a greater'or less number of nail-de liveries. Each of these nail passages or tubes has inserted into it or connected with its open upper end one of the flexible tubes bfiinto which the nails to be driven into the heel are dropped with their heads leading. The springs connected with the deliveries, Fig. 4, tend to move said deliveries toward the pattern. When placing a pattern in working position, it may be introduced between the deliveries and turned and fastened in position, and as the plate is turned into its op erative position it will act against the de1ivcries and push them outwardly. If desired,

the tubes may be acted upon by hand and pushed back when putting a pattern-plate in position. i

I have provided a series of patterns or plates 20 21 22, each composed, preferably, of steel, having a series of notches, as 23, located irregularly each with relation to the other, the bottoms of said notches at one side of the plate being more or less separated from the bottoms of notches at the other side of the pattern, so that each pattern when used may receive in each one of its notches a delivery and position said deliveries in the desired curve or path with relation to the holes in the nail-carrier, that depending upon the particular shape of the pattern-plate, there being as many different patternplates as there are nailings to be made in the heels of the shoes being produced.

In Fig. 4 the pattern-plate 20 positions the funnel-shaped nail-holding portions of the pattern-plates 21 or 22 used theywould position the said deliveries in a'difierent curve or line, the springs 18 yielding to allowthis change of position of the deliveries.

From the foregoing itwill be seen that the nails dropped into the tubes will readily enter the deliveries and that the deliveries, by applying to them, as represented in Fig. 4:, a pattern-plate of the desired shape, may be moved one'with relation tothe other to occopy a position in any desired line, such lines, however, corresponding with one of the series of nailings depicted or provided for by the positions of the holes in the nail-carrier and in the top of the nail-block, as referred to with relation to Fig. 3:

In Fig. '11 the pattern is shown as composed of two plates and 3l,.which may be pivoted together at 32, each of said plates being suitably notched to engage a delivery, and the deliveries to operate with this class of pat-' tern,it acting to push the deliveries one toward the other, must be acted upon by a spring which will normally pull the deliveries apart.

or separate them one from the other, and to effect this one end of each of said springs may be connected to a series of pins 14 and to studs 17 erected on the plate 12 at the opposite ends of the slots in which the pins 14 travel.

Believing myself to be the first to employ a series of easily-movable deliveries under the control of a pattern-plate, so that by the use of one or another'plate differing in shape said deliveries may be readily and instantly shifted or-changed from one into another position to correspond with any or the desired usual nailing outline, this invention is not to be limited to the exact shape shown for the deliveries, nor to the means for supporting them on or with relation to the plate 10?, for the particular shape of the deliveries and their supporting means may be variously modified and yet be within the scope of my invention.

This invention is useful in anymachines where nails are to be driven in other than a straight line. 7

Having described my invention, what I claim as new, and desire to secureby Letters Patent, isy 1.- In a nailing-machine, a series of-mov able nail-deliveries, means to support said deliveries, and a pattern adaptedto cooperate with said deliveries to maintain the latter in" erate with said deliveries to maintain them in position to accord with a' desired form or outline of nailing, substantially as described.

3. A plate, a series of deliveries mounted" loosely thereon and springs to normally move said deliveries in: one direction, combined with a pattern plate or device adapted to be applied to said. deliveries'to place them at' proper distances apart and maintain themin.

the position designated by the contour of said pattern-plate, said springs operating to maintain the deliveries in contact with the pattern-plate, substantially as described. A

4. In a nailingmachine, a series of naildeliveries to inclose nails,'-means'to support said deliveries, and a pattern to position simnltaneously all said deliveries in the desired outline for nailing.

5. In a 'heeling-machine, a foot-plate, nail-- A assorting mechanism, a series of independent movable nail deliveries, a series offlexible tubes connected each with" one'of said nail-' deliveries and with said'nail-assortin'g mechanism, and a pattern 'toposition independ ently said nail-deliveries according to the arrangement of'holes to be 1 filled with nails and the outline of nailing desired. l 6. In a nailing-machine, a series of springheld nail deliveries, and a pattern plate adapted to act simultaneously on and position each delivery independently.

--7. Ina nailing-machine, a series of pivoted, slidable, normally yielding nail deliveries, and a pattern-plate to simultaneously insure the placing of said nail-deliveries in position to enable nails to be arranged in accordance with a desired outline.

8. In a nailing-machine, a plate, a series of and-pinconhection between said plate and arms, and a'pattern-plate acting against said.

nail-tubes to position them and their armsin accordance with the outline of nailing desired.

9. In anailing-machine, series of independently-m ovable nail-deliveries, combined with a pattern having a series of notches to receive and determine the position of said nail-deliveries to accord with a desiredout line of nailing; I i
